FlLLING-REPLENISHING MECHANISM FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 726,493, dated April 28, 1903.

Ap li ati fil d February 24, 1903. Serial No. 144,597- (No model) To aZZ whom it may concern:

Be it known that I, BINGHAM F. S. AUsTIN, a citizen of the United States, and a resident of Gastonia, county of Gaston, State of North Carolina, have invented an Improvement in [*illing-Replenishing Mechanism for Looms, of which the following description, in connec tion with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to mechanism for antomatic-ally replenishing the shuttle with filling and of the type forming the subject-matter of United States Patent No. 529,940.

The filling-carriers or bobbins are mounted in an intermittingly-movable feeder, and they are transferred therefrom one by one to the shuttle by suitable mechanism including a transferrer. At the time of transfer the filling carrier is moved downward from the feeder and it is guided at one side by a fixed abutment, and on the opposite side a springcoutrolled inherently-rigid finger or buffer has been employed to support and guide the filling-carrier-as, for instance, in United States Patent No. 664,790 the abutment and buffer forming a species of discharge-throat.

In practice it has been found that this buffer will break after a certain amount of usage, and such breakage is attributed to the probable crystallization of the metal due to the shock imparted thereto when returning to normal position after the transfer of a fillingcarrler.

My present invention has for its object the production of a light inherently-resilient buifer of simple construction and which will not be subject to the objection hereinbefore mentioned.

The novel features of the invention will be described hereinafter, and particularly pointed out in the following claims.

Figure 1 is a side elevation and partial section of a portion of a filling replenishing mechanism of the type referred to, with one embodiment of my invention operatively applied thereto. Fig. 2 is a detail showing the manner of mounting the buffer on the stand of the replenishing mechanism, and Fig. 3 is a perspective view of the buffer detached to more clearly show the construction thereof.

The lay A the shuttle S, the breast-beam A having secured to it a stand A on which is mounted the filling-feeder, comprising, es-

sentially, two parallel and connected disks (only oneof which, as a, is herein shown) to rotate on astud Ct, rigidly secured to the stand A the transferrer f, the means to actuate it to transfer one by one the fillingcarriers or bobbins b from the feeder to the shuttle, and the means for intermittiugly rotating the feeder may be and are all substantially as shown in Patent No. 664,790 referred to.

An abutment h, secured to the stand A is adapted to guide or direct one side of the head of a filling-carrier during transfer, as in said patent, this abutment forming one side of the discharge throat leading from the feeder to the shuttle.

In accordance with my present invention a headed stud a is secured to the lower part of the stand A opposite the abutment and below the circular flange cf, Fig. 1, near the lower end thereof, and on this stud the buffer is mounted. The buffer is made of sufficiently stout spring wire, which is bent to form an elongated loop m, the wire being then coiled at theinner end of the loop, as at m, to form spring-coils, through which the stud 00 is extended. The two spring-coils are located coaxially end to end, and therefrom the two parts of the wire are carried in parallelism and bent laterally, as at 2 2, Fig. 3, and extended back of and axially with the coils to the bends 3 3. ends at 4 of the wire are upturned at an acute angle to the loop, as best shown in Figs. 1 and 2, one end being shown in Fig. 3 as slightly bent laterally, as at 5. When the bufier is mounted on the stud a the loop-like portion 071 extends below the flange a toward the abutment h and part way into the path of a filling-carrier when transferred, While the parts between the bends 2 3 extend under and around the lower edge of the stand A The two ends 4 of the wire are thus upturned back of the stand and rest against an ear a projecting therefrom. A headed bolt n is in- At this point the twoserted between the ends 4: and passes through a hole in the ear and is secured in place by a nut W, a washer n being shown in Fig.2 as interposed between the wire ends 4 and the bolt-head. By tightening up the nut the said ends are rigidly clamped to the ear and the buffer-loop m is maintained in operative position by the coils m and the resiliency of the wire. The olfset 5 serves to separate the Wire ends 4 for the passage of the bolt between them. When a filling-carrier is transferred, the buffer m is pushed downward, yielding to the pressure, and acting upon the adjacent side of the head of the filling-carrier guides and supports it as it is moved down through the discharge-throat. As soon as the transferrer rises after a transfer the I inherent resiliency of the wire,acting through the coils m and the portions of the wire between them and the ear a causes the buffer to return to normal position without shock or hitting against any solid part of the apparatus.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. Filling replenishing mechanism for looms, including an intermittingly-movable feeder to hold a plurality of filling-carriers, a transferrer, and a discharge-throat through which the filling-carriers pass, said throat comprising a fixed side or abutment, and an oppositelylocated resilient and angularlymovable buffer to guide and support the filling-carrier as it is transferred.

2. Filling replenishing mechanism for looms, including an intermittingly-movable feeder to hold a plurality of filling-carriers, a transferrer, and a discharge-throat through which the filling-carriers pass, said throat comprising a fixed side or abutment, and a resilient, angularly-movable loop-like buffer mounted to extend beneath and support, and to guide a filling-carrier when transferred.

3. In filling-replenishing mechanism, an intermittingly-movable feeder to hold a series of filling-carriers, a transferrer, a fixed abutment at one 'side of the endmost filling-carrier of the series, and a resilient, spring-controlled buffer having a fixed support and extended toward the abutment, to support and guide a filling-carrier and yield when the latter is transferred from the feeder.

4. In filling-replenishing mechanism, anintermittingly-movable feeder to hold a series of filling-carriers, a transferrer, a fixed abutment at one side of the endmost filling-carrier of the series, a buffer located opposite said abutment, the buffer consisting of a piece of wire bent to present a loop, spring-coils, and an upturned tail portion, a fixed support extended through the spring-coils, and means to engage and fixedly hold the tail portion.

5. Filling replenishing mechanism for looms, including an intermittingly-rotatable feeder to hold a series of circularly-arranged filling-carriers, a transferrer, a fixed abutment adjacent one side of the filling-carrier next to be transferred, and an oppositely-1ocated yielding and resilient buffer adapted to support and guide the side of the fillingcarrier opposite the abutment at the time of transfer.

6. Filling replenishing mechanism for looms, including an intermittingly-rotatable feeder to hold a series of circularly-arranged filling-carriers, a transferrer, a fixed abutment adjacent one side of the filling-carrier next to be transferred, and an oppositely-lo- 1 cated buffer consisting of a loop of resilient wire yieldingly mounted and adapted to extend below the endmost filling-carrier of the series, the buffer supporting and guiding the side of the filling-carrier opposite the abutment and yielding to the movement of the filling-carrier when transferred.

7. A buffer for supporting and guiding a filling-carrierduring transfer in filling-replenishing mechanism for looms, consisting of a resilient, loop-like member having an integral retracting-spring, and a fixed support upon which the bulfer is pivotally mounted.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
